Petunia Plant Named ‘Narupetu Double Apple’

ABSTRACT

A new and distinct cultivar of  Petunia  plant named ‘Narupetu Double Apple’, characterized by its trailing plant habit; vigorous growth habit; freely branching and flowering plant habit; long flowering period; medium-sized double red purple-colored flowers; and good garden performance.

Botanical designation: Petunia×hybrida.

Cultivar denomination: ‘Narupetu double apple’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia, botanically known as Petunia×hybrida and hereinafter referred to by the name ‘Narupetu Double Apple’.

The new Petunia is a product of a planned breeding program conducted by the Inventor in Yonago, Tottori, Japan. The objective of the breeding program is to create new Petunia cultivars with attractive foliage and flower coloration.

The new Petunia originated from a cross-pollination made by the Inventor in June, 2002 in Yonago, Tottori, Japan of a proprietary selection of Petunia×hybrida identified as code number 02P-R-1, not patented, as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code number 02P-DW-1, not patented, as the male, or pollen, parent. The new Petunia was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Yonago, Tottori, Japan.

Asexual reproduction of the new Petunia by terminal cuttings in a controlled environment in Yonago, Tottori, Japan since October, 2004 has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Narupetu Double Apple has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Narupetu Double Apple’. These characteristics in combination distinguish ‘Narupetu Double Apple’ as a new and distinct cultivar of Petunia::

-   -   1. Trailing plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching and flowering plant habit.     -   4. Long flowering period.     -   5. Medium-sized double red purple-colored flowers.     -   6. Good garden performance.

Plants of the new Petunia can be compared to plants of the female parent selection. Plants of the new Petunia differ primarily from plants of the female parent selection in flower form as plants of the female parent selection have single flowers.

Plants of the new Petunia can be compared to plants of the male parent selection. Plants of the new Petunia differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Petunia are more trailing than and not as         upright as plants of the male parent selection.     -   2. Plants of the new Petunia and the male parent selection         differ in flower color as plants of the male parent selection         have white-colored flowers.

Plants of the new Petunia can also be compared to plants of the cultivar Burietta Rose Vivid Pink, not patented. In side-by-side comparisons conducted in Yonago, Tottori, Japan, plants of the new Petunia and the cultivar Burietta Rose Vivid Pink differed in the following characteristics:

-   -   1. Plants of the new Petunia were shorter, but broader than         plants of the cultivar Burietta Rose Vivid Pink.     -   2. Plants of the new Petunia had larger and broader leaves than         plants of the cultivar Burietta Rose Vivid Pink.
